WLL190T-2
Max. Teach-in
Teach-in to maximum sensitivity. Stable
object detection without background
effect.
1-point Teach-in
Teach-in  quick and easy for standard
applications.
2-point Teach-in
Exact switching threshold adjustment
at the object and of the environment.
Ideal for applications with small system
reserves.
Auto Teach-in
Fully automatic switching threshold ad-
justment of moving objects. Even falling
or tiny objects are reliably detected.
Zone Teach-in
This so-called window technology learns
the object within a definable bandwidth
of the switching threshold. Ideal for the
detection of marks, or simultaneous fore-
ground and background suppression.
Teach-in of transparent objects
Teach-in with minimum sensitivity, reliably
detecting glass, films or small objects
Fast and reliable programming menu driven and at the push
of a button: sensor properties and parameters are individually
determined directly on the sensor.
Universal or individual
application solutions.

Photoelectric switch for fibre-optic cables WLL190T-2 
Easy handling, structured functions and maximum
functionality.
The photoelectric switch for fibre-optic cables WLL190T-2 with the SICK
fibre-optic cables is especially suited to detecting very small objects,
objects in front of interfering backgrounds, and transparent and moving
objects. Fibre-optic cables are ideal for use in installations where space
is restricted.

Second output or input
In addition to the switching output Q1, the second
connection can be assigned as the second swit-
ching output Q2, alarm output, external Teach-in
input or for resetting the counter.
Version with analogue and switching output
Suitable for many different applications, such as
position control.
From monitoring to power control.
Monitoring simplifies many things, and technical highlights
provide many options, always enabling easy commission-
ing and permanently reliable operation.

Adaptation of the measuring range to the service signal,
for optimum resolution.
Especially for detecting:

(spreading the measuring range),
 close objects/objects with high reflectance
(preventing saturation).

The power of the sender LED can be adjusted in three

For standard applications: Teach-in and the commissioning is complete.
The automatic learning with Teach-in is always the first step. The six different Teach-in versions can
be quickly and easily selected. For standard applications, the settings automatically selected by
the sensor are sufficient for stable operation.
Manual adaptation of the switching threshold
Manual, step-by-step modification of the switching
thresholds by operating the arrow keys. After a few seconds,
the display automatically jumps to the operating mode.
Within the zone Teach-in, first, the arrow keys are used to select the
close or far range, and then the respective switching threshold is
adjusted via the arrow keys.
